STONE-GATHERER.

Application tiled May 7, 1918.

To all whom t may concern:

Be it known that I, THOMAS R. MANDER- soHniD, a citizen of the United States, residing at Terrebonne, State of Oregon, have invented certain new and useful Improvements in Stone-Gatherers, of which the following is a specification.

This invention relates to harrows and dig'- gers, and more especially to stone gatherers; and the object of the same is to produce a machine for gathering the stones and pebbles at and just beneath the earths surface and conveying them to a wagon driven alongside.

Other objects will appear from the following specification and claims, and attention is invited to the accompanying drawings wherein Figure 1 is a plan view of this machine complete, and

Fig. 2 a side elevation partly 1n longitudinal section,

Fig. 3 is a rear end elevation of the delivery box, and

Fig. 4 is a sectional detail of one of the disks.

A pair of main wheels 1 mounted on an axle 2 supports spaced beams 3 within which an endless carrier moves upwardly as shown. This carrier may be a slatted apron 4 traveling over upper and lowerv rollers 5 and 6, one of said rollers having a sprocket wheel 7 connected by a chain belt S with another sprocket wheel 9 and a counter shaft l10, which latter has gears 11 connecting it with power gears 12 on the hubs of the main wheels. At a suitable point the countershaft contains a backing ratchet indicated at 13 so that the main wheels 1, 1 may travel at different speeds as when the machine is turning corners. Supports 15 extend to the rear from the upper ends of the beams 3 and carry a delivery spout as indicated at 16 1n Fig. 3. This is a trough inclined downward in both directions from its center which is immediately behind the transverse center of the endless carrier shown in this view as the belt or apron 4. At the highest point or ridge of the inclined bottom of this trough a triangular element 17 is pivoted at 18. In this view said element is shown in full lines at the left and in dotted lines at the right. As in full lines it will of course shed toward the right in this view whatever material is dumped onto it from the carrier, whereas when it is turned over to the right- Specication of Letters Patent.

it would shed all of the material to the left, and therefore the delivery spout may be caused by the setting f this element to deliver the material into a wagon along either side of the machine. The lower end of the fralne structure consisting of the two beams 3 carries a scoop indicated broadly at 19, and the same is intended to travel just beneath the earths surface and pick up stones and deliver them onto the carrier, by which latter they are conveyed to the delivery spout as will be clear.

Secured to the forward end of the main framework is a pair of brackets 20 from which rise posts 21, and from the posts two members 22 extend forward and converge toward each other to constitute a tongue, their front ends being attached to a plate 23 to which in turn is attached the draft not necessary to illustrate in the present i11- stance. Secured at its center upon said plate is a long cross bar 24 whose extremities are connected by oblique bars 25 with the brackets 2O above referred to. Another bar 26 underlies the tongue and is attached to the members thereof as seen in Fig. 1, and at the sides of the tongue it is bent forward into oblique bars 27 which are connected with the cross bar 24 just inside its ends as shown, the connection being by preference a special one so that it may carry a shovel 2S rigidly or adj ustably and of any appropriate shape and size. In rear of each shovel and preferably journaled on the oblique bars 25, are disks 29 inclined obliquely to the rear and overlapping each other slightly, and by which the material picked up by the shovel is passed back onto the scoop 19 for treatment in a manner yet to be described. All of the structure just described as carried by the brackets 20 is supported at its rear end from the main frame bars or beams 3, and at appropriate points this structure itself may be supported on other wheels not neces'- sary to illustrate. However, in any event I prefer to support this structure by guy rods 30 leading from the main frame at a point near the aXle 2 to the upper ends of the posts 21 where these rods are provided with a series of openings 31 adjustably engaged with a long bolt 31 as best seen in Fig. 1. Forward of the posts are guy rods 32 leading downward to a truss rod 33 whose ends are attached as at 34 to the cross bar 24 in any appropriate manner. By this superstructure the elements carried by the 2 p v Y y 1,293,239.`

brackets 2O forward of the main frame may or of rods so as to give it strength without unduly adding to its weight.

In use theY parts are setso that the shovels, the lower4 edges of the disks, and the point of the scoop 19 willo all travel justa little beneath the earths surface. When draft is applied to the plate 23 and the entire ma-v chine movedy forward, rotation of the main wheels causes the upward travel ofthe `endless lbelt `or apron a and projects the shovels 28 forward .through the earth just at lthe surface of the same, while the lower edges of the disks 2:9 valso cut into the earth at about the same plane. The result is that a wide swath or path Yis cleared of gravel", pebbles, stones Y and other accumulations which are undesirable, all of Vwhich are passed back from one disk to another until they are .delivered to the scoop 19; This picks them up and delivers them to the endless carrienwhi'ch in turn delivers them to the delivery spout shown in Fig. 3, and Vfrom. theVV latter they are dropped to either side into la-w'vagon driven valongside this'maohine.

The foregoing description and the drawings have reference to what may be considered the preferred,or approved form of my invention. It is to-be understood that I may make such changes in construction and arrangement and combinationof parts, materials, dimensions, et cetera as'may prove eX- pedient and fall within the scope of the appended claims. f

Having thus fully described my invention, Awhat I claim as new and desire to secure by Letters Patent, is l. In a stone gatherer, the combination with a main framework mounted on wheels, ascoopy carried at the lowerend of the frame@ work, andmeans for elevating and deliver ing the material received by the scoop; ofV

bars extending obliquely forward from said main frame, and shovels and disks on said bars for gathering stones at and near the All of this superstructure also. IV would prefer to make of angle ironl earths surface and p-assing them back to Ysaid scoop.

2. In a stone gatherer, the combination with.l a main framework mounted on wheels, an upwardly moving endless carrier disposed said framework and driven, by Athe rotation of the wheels, land a scoop carried at the lower'- end! of the framework and delivering stones to the carrier; of bars eX- tending obliquely forw'ardfrom said main frame', jand shovels and dis-ks on said barsV forgathering vstones at and near the earths surface and passing thembackto said scoop.

3.. In a stone gatherer, the combination with a main framework mounted onwheels, an upwardly moving Iendless carrie-r disposed in Said framework Vand -driven by the rotation of the wheels, and a scoop carried at the lower end of the framework and dei livering stones to the carrier; of bars -eX-l tending obliquely forward' from saidL main frame, a cross Ibar connecting their forward ends, a tongue lconnecting the main frame with sai-d cross bar and carrying means for A attaching the draft, shovels near the ends of said cross bar, 'and' means 'on said oblique bars for passing material from the shovels Y rearwardly 'to said scoop'. y Y

Y 4. In a stone gatherer, the combination withV a main frameworkmounted on wheels, an upwardly moving endlessjcarrier ydisposed inV said framework and: drivenby the rot-ation of the wheels, and a sc'oop 'carried at the lower end of the framework and delivering stones, to the carrier; of brackets carried by the front end of said main framework, posts upstandin'g therefrom, a skeleton Vframework structure also carried' by said brackets, means thereon for gathering ysaid stones and delivering them to saidv scoop, and guy members connecting the main framework with 'the upper ends of the posts Y and thelatter with said skeleton framework, c

for the purpose set forth. l Y
